Visit petapixel.com and see: Concept Design of a Leica R10 camera.
The best thing on the R10 render was the V Hasselblad-like strap connectors. With these connectors one can take-off/put-on the strap in a split second. These connectors are unsurpassed after 30 years or more. I always wondered why Canon or other dslr maker has not produced them yet now that DSLR’s are now tripoded so often.
